Meteor Method Pattern

calling-method.js

// On the client-side.

Template.exampleTemplate.events({
   'submit form': function(e, t) {
      var dataToAddToDatabase = t.find('input.example').value;
      
      // This will work just fine, but delegates the insert to the server.
      Meteor.call('processFormData', dataToAddToDatabase, function(error, response){
         // Do something with feedback.
      });
      
      // This would fail, throwing an error in the console. Even if I call this *from* the console, it fails.
      ExampleCollection.insert({key: dataToAddToDatabase});
   }
});

collection.js

ExampleCollection = new Meteor.Collection("example-collection");

ExampleCollection.allow({
   insert: function() {
      // Deny all client-side inserts.
      return false;
   },
   update: function() {
      // Deny all client-side updates.
      return false;
   },
   remove: function() {
      // Deny all client-side removes.
      return false;
   }
});

ExampleCollection.deny({
   insert: function() {
      // Deny all client-side inserts.
      return true;
   },
   update: function() {
      // Deny all client-side updates.
      return true;
   },
   remove: function() {
      // Deny all client-side removes.
      return true;
   }
});

server-method.js

// On the server-side.
Meteor.methods({
   processFormData: function( dataToAddToDatabase ) {
      ExampleCollection.insert({key: dataToAddToDatabase});
   }
});
